Cholesterol – angel or daemon?
Cholesterol is a fat molecule manufactured in the liver and also found in some foods (mostly animal fats). It is an important structural component of cell membranes, an essential precursor of Vitamin D, certain hormones (particularly sex hormones) and bile acids.
Even though cholesterol is essential to the normal function of the body, too much can cause harm to your heart and circulatory system, through atherosclerosis (deposits of cholesterol in your blood vessels), a condition that if ignored, can lead to fatal consequences.
Frequently Asked Questions
Is there really a good and a bad cholesterol?
There are five major groups of lipoproteins, ordered by density, from least dense to most dense. But only two of them are needed to assess the risk of cardiovascular disease: Low Density Lipoprotein (LDL) – the bad cholesterol – and High Density Lipoprotein (HDL) – the good one.
What about triglycerides?
Raised triglycerides are an independent risk factor for heart disease and diabetes.
What are the causes of high cholesterol?
- Diet and lifestyle
- Sex, age and ethnicity
- Medical history
Which foods are bad for my cholesterol levels?
- Full dairy cream
- Animal fats – butter, margarines, ghee, lard, dripping, suet
- Fatty meat
- Processed meat products
- Coconut and palm oils
Which foods are good to lower LDL cholesterol and raise HDL?
- Soya foods
- Nuts, seeds, whole grains
- Oats and barley
- Lots of fruits and vegetables
Do I have to avoid every food that is rich in cholesterol?
You don’t have to restrict foods low in saturated fat but rich in cholesterol like lean meat, liver, prawns, lobster or egg yolk. You do need cholesterol in your diet after all.
Is diet enough to keep bad cholesterol at bay?
- avoid a sedentary lifestyle
- avoid smoking and alcohol
- manage your weight
- reduce your waist circumference.
What are the symptoms of high cholesterol?
- Heart attack
- Intermittent claudication – pain on walking
Do I really need medication for my high cholesterol?
Could I inherit high cholesterol from my parents? It is treatable?
However, the treatment is the same: first line, changing lifestyle, and if this doesn’t work, medications.
Statins are the first type of medication doctors usually prescribe to lower LDL and triglycerides. Studies found that they reduce cardiovascular disease and events alone and are used both in primary and secondary prevention.
Among side effects, muscle pain, intestinal problems and high blood sugar are the most common.
This type of drug is recommended as second line of therapy, after an unsuccessful trial of statins. The main mechanism of action is decreasing absorption of cholesterol in the small intestine. Ezetimibe combination drugs are also marketed for better tolerance. Contraindications include previous allergic reactions and severe liver disease, especially in statin combination.
Fibrates are used for a number of metabolic disorders, mainly hypercholesterolaemia and their primary target is triglycerides and consequently boosting the HDL levels. Examples include Fenofibrate and Gemfibrozil. Like Ezetimibe, they can be used alone or in combination with statins.
Safe, real prescriptions for Cholesterol.
This is a simple test of measuring the levels of cholesterol in the blood using either a venous sample or a capillary (pinprick) test – where only a small drop of blood from your finger is used and then inserted in a calibrated device using a strip or cassette. The result from the capillary test can be ready within minutes.
Full lipid profile
The lipid profile or lipid panel is a complete cholesterol test used to measure the “good” cholesterol, the “bad” cholesterol and triglycerides in your blood. It can be performed by any healthcare professional and they usually take a venous sample from your arm, then send it to the laboratory and waiting about 48 hours for the results. For best results, you must not eat at least 8 hours prior to the test.
This prediction algorithm for cardiovascular disease uses data like age, blood pressure, smoking status, lipid panel, BMI and other traditional risk factors. It can be found online at qrisk.org and it is updated annually because of changes in population characteristics, improvements in data quality and changes in requirements for how the risk prediction scores can be used, for example changes in age ranges.
A QRISK score over 10 – that means a 10% risk of a cardiovascular event to occur in the next 10 years – indicates that a lipid lowering therapy should be considered.
